e it lowwnthe .1, nwnsrwi 'W- Beam? :reitizenof the llnitedaStotes and aresident of Indianapolis, county of lvlarion engl State of Indiana, have :inventeda certain new and useful Sealing- .Gonstruction; and I ,do hereby deelarethatthe gtollowing i-sa iull, ,olee r, and exact description thereof, reference heing had ;to the accompanying drawings, in which like mnnerals refer to like parts.

Hlhis .inuention relates .;.to .a'se jiug co n struction' efer-doors, windows and the like, and ,is rOtE a ellaracter similar gto thet disclosed .in my prior Patent No. 1,311,775 .datedJulyQS),19 19.

Thei i f chi Q 0 t 1 ese -.ii .1t on is. to construct a sealing means which is not only djustahle,ifidesired hut. whieh is like I wise substantially ies-l; ,proof .in that it Seals e join by s mu t n o ly c tacting,

.two adjacent suriac fi Of .two angularly ,poy

.sitioned faces. V

lhnotherobject of the invention is to pro duce an articulated sealing ,eonstruotion which provides 3. substantially,continuous sealing strip, the articulation bein g provided f dju t ity t tak care (of wa m-nea .oneior both ofithe faces andtheir respeetive relative Vpositions.

The chief deature of the invention icon t n Pr s d ngasunp r inginer niupon which is mounted, ,asgloy uneans of position.- ing in grooves, pair of sealing ;.stri1 3 s of flexible materiel-such .as ,felhor the like, and which extend angule-rly of each other, and as ,herein disclosed, transversely of each other. i

Another feature 9f the invention consists in the formation of .two fidj flcen t ,ends .of the supporting members before lnentioned, and gthe -formation of complementary surfaces upon an intemnediete hinge or joint sforn ing bracket .which ,is not only adapted to forum an articulatedeonstruotion withsaid adjacent supporting members, .but .isadapted to simultaneously ,position and .maintain therein, ,the -;sealin g JRQZLDS between the ends ofthestrips. Furthermore, the,hinge bracket Y or joint is also iadapted .to clamp theseaidug support to the supporting surface 'to which it is ,attaehed. V

The full ,nature of the .inuention .will be :understood from the, ccompanying draw.-

iugs and the following description and claims. v i

ierred construction-and .11 indicatesthe toor 4 which maybe .inounted in any suitablenia r near, but generally isunounted npon rollers and slides lengthwise oi the door casing when heing opened ,or closed, as is ,the vease with structures of {this class. In ,kilnspf the .character described, the doors and .cas ings frequently warp, and such warpage causes a crack or aperture between the gdoor Open ng an c o u e, w ch woul P r it the .e scapeof the-heated air and wouldpernitthe,entranceofi cold .air. This air trans- }ference would seriously effect not only ,the .luinherl eing dried,:h ut would also be .unecon oniiwl. The .present means,- "therefore, isidesignechto ,providea positive seal between .the deonandthe doorcasing independentkof (the degree of warpage therehetween. Such ,a positive seal .is secured by utilization of a multiple ela nping action and. a ,inultiple contact, seal in the; arrangen'ient whereby the ,two :lCljacent and angularly gpositioned .faces of .the seal-are simultaneously engaged by .a multiple acting clainp to simultaneously seal .the ,joint between said two werpedsurfaces and thus prevent- .the transference of .air between the .kiln and the outside.

,I-Ierein the ,sealing construction is shown including-a .base orsupporting member 12, vwhich is shown provided with two longi- ,tudinally .extendingrslots or grooves .13 ,and

:14, and these slots are herein shown rec iangular and are positioned upon two transversely positioned faces and are transversely positioned also. The slot 13 carries a longitudinally extending sealing strip 15 of suitable material, such as felt or the like, which material projects outwardly from the slot in which it is anchored or otherwise suitably secured and into engagement with'the door 11. A similar strip 16 is similarly positioned in slot 14: and similarly projects from said slot but into engagement with the casing 10. Herein (see Figs. at and 5) an L- shaped clamp 17 is adapted to engage simultaneously two anchored faces of the supporting base 12 and cause the strips 15 and 16 to sin'lultaneously engage the door 11 and casing 10. Such clamping engagement of the supporting base is secured by a clamping member 17 being elongated as at 18, and provided with an elongated slot 19. Posiiioned in the slot 19 and suitably secured to the casing 10 in this instance, is a screw 20, with which is associated a washer 21, as shown. It will be readily apparent that independent of the warpage of the casing 10 and the door that if the kiln is closed, the sealing strip base 12 may be adjusted so as to simultaneously contact both of the adjacent surfaces of the door and the casing, therefor, and thus provide a sealed or substantially air tight joint therebetween.

If desired, the before mentioned sealing construction may be extended along the side of the door continuously from end to end. and in this event the base member 12 should be sufliciently resilient through its relatively long length so as to yield and thus adj ustment can be made throughout the length of the joint. To positively insure such flexibility, however, an articulated construction' is herein disclosed.

The aforesaid articulated construction includes a plurality of sealing strip sections, which are suitably formed at their adjacentends and associated with said formed ends is a member which simultaneously serves as a clamp, a sealing-strip positioning device and a joint. Herein the complementary formation is a tongue and groove arrangement, and herein (see Figs. 2, 8, 4 and 5) the groove is formed in the end of the base 12 and is indicated by the numeral 22. Herein the same is shown rectangular but any preferred outline may be employed. The combination clamping bracket and joint consists of a body portion 25, having a projecting ledge 26 upon its upper surface, and said projecting ledge is adapted to form a registering angular arrangement with the base 12, as shown clearly in Fig. 4. Projecting oppositely from each other and the body 25, are a pair of projections 27, which projections are each receivable by one of the notches, grooves or slots 22. Herein the body 25 is also shown with oppositely and laterally extending projections 28, which over-lie the projections 27 and thus serve to engage the outer face of the sealing strip base 12 for simultaneously anchoring said base, thereby eliminating the use of an adjacent clamp construction, previously described and indicated particularly in Figs. 4 and 5.

The under-face of the body portion 25 is herein shown provided with a registering groove 29, which groove is adapted to receive the sealing strip 16. It will be understood that the sealing strip 15 is positioned in the registering angle formed by the body portion 25 and the angular projection 26. EX- tending rearwardly from the before mentioned joint construction is a wing portion 30, substantially similar to the wing extension 18, previously described, and said wing 30 includes the usual elongated slot 31, with which is associated the clamping bolt 20 and washer 21. If it is desired, the supporting base may be articulated, that is, formed in sections and the sealing strip continue throughout the length of one longitudinal surface. This is the arrangement shown in Fig. 4. If, however, it is desired, the sealing strip may be severed and each supporting base be provided with its particular sections of sealing strips. In this instance the construction is formed as shown in Figs. 2 and 3. It will be readily apparent, therefore, that the clamping member shown in the bottom portion of Fig. 4 prevents leakage between joints, since it in reality includes substantially the same construction as the seal ing base 12 so far as positioning the strips is concerned.

The invention claimed is:

1. The combination with a wall member and an adjacent closure member, of a sealing construction for the same including a plurality of articulated supporting bases, a jointbetween adjacent ends of a pair of said supporting bases, sealing means carried by said supporting bases, said joint having co-operating portions intermediate the ends of said supporting bases for engaging the end projecting portions of the sealing means and maintaining the same in sealing position.
